Chassis Mount (143-146 Series)

NOTES:

*1) For output transformers this figure is maximum unbalance.

CHASSIS MOUNT

AUDIO TRANSFORMERS

Economical, open, two hole horizontal bracket mount.

•

Insulated, color coded flexible leads, 4" long minimum (143, 144 & 145 Series)

•

or 3" long minimum (146 Series).

For a similar, P.C. board mount version, refer to our 148 & 149 Series.

•

Frequency response 150 Hz. to 15 Khz. (+/- 1 db, reference 1000 Hz.)

•

When operating at impedances below nominal, power capability and the

•

frequency spectrum are proportionately lower, conversely, at higher impedances

power capability and frequency spectrum will be proportionately higher.

Net weight: 0.5 oz. (143, 144 & 146 Series) & 1.4 oz. (145 Series).
